Welcome to the community!
What type of plan do you have: pre-paid or post-paid? Does your plan already include some data? Unfortunately, I don't think Fido offers a Data Passes anymore (see here).
If you you have a post-paid plan which doesn't already include some data, you'll need to switch to a plan which includes data. On the other hand, if you have a pre-paid plan which doesn't already include some data, there are monthly data add-on options (see here).
If you would like to discuss your options with customer service, you would need to contact customer service. Alternatively, you might consider sending @FidoSolutions a PM. Once they verify some information, they'll also be able to access your account.
Hope this helps 😀
